Description

Technical Field

[0001] This utility model relates to the technical field of fixed fuel particle size control, and in particular to a combustion particle size control device adapted for solid fuel combustion. Background Technology

[0002] Solid fuels are substances that are solid at room temperature and pressure and can be used to generate heat or power. Solid fuels are a large category of fuels, consisting of solid combustible materials that can produce heat or power. Most contain carbon or hydrocarbons. Natural examples include wood, peat, lignite, bituminous coal, anthracite, and oil shale. Processed solid fuels include charcoal, coke, coal bricks, and coal briquettes. There are also some special types of solid fuels, such as solid alcohol and solid rocket fuel.

[0003] The combustion intensity of fixed fuel is controlled by screening solid fuel through sieves of different mesh sizes, intercepting fuel particles that do not meet the particle size requirements, thereby achieving control over fuel particle size.

[0004] However, the existing combustion intensity and control devices, which use screens to intercept unqualified solid fuels and then crush the intercepted fuels to the appropriate particle size before putting them into combustion, will prolong the entire production process and affect production efficiency. Furthermore, operating the screening and crushing equipment requires specialized operators, which increases labor costs. Utility Model Content

[0005] The purpose of this invention is to provide a combustion particle size control device adapted for solid fuel combustion, so as to solve the problems mentioned in the background art.

[0006] The technical solution adopted in this utility model is:

[0007] A combustion particle size control device adapted for solid fuel combustion includes: a feeding assembly (1);

[0008] The feeding assembly includes: a control tube;

[0009] Control component, the control component includes:

[0010] The filter plate is fixed inside the upper part of the control tube;

[0019] Optionally, a crushing roller is rotatably installed inside the crushing frame, and a motor is fixed on one side of the crushing roller. The first connecting pipe and the second connecting pipe are obliquely fixed on one side of the control pipe.

[0020] Optionally, a fixing platform is fixed to the lower surface of the electric push rod, and one side of the fixing platform is fixed to the outer surface of the control tube.

[0021] Optionally, an adjustment assembly is also included; the adjustment assembly includes: a mounting groove, which is opened at the upper front end of the control tube and located in the middle of the filter plate; a placement groove, which is opened in the middle of one side of the filter plate and corresponds directly to the mounting groove; and an adjustment plate, which is slidably placed inside the mounting groove and the placement groove.

[0022] Optionally, the surface of the adjustment plate is provided with a second filter hole, and the diameter of the second filter hole is smaller than that of the first filter hole, and the first filter hole and the second filter hole are directly opposite each other.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] After the fixed fuel is fed into the control tube through the feeding and control components, the filter plate sends the fixed fuel with the required particle size into the combustion furnace. The fixed fuel with the required particle size remains on the upper surface of the filter plate. Then, the electric push rod is activated by the external controller. The electric push rod drives the push plate to move on the filter plate, pushing the larger solid fuel particles into the crushing trough. The fixed fuel enters the first connecting pipe from the crushing trough and then flows into the crushing frame from the first connecting pipe. Then, the motor is activated, and the motor drives the crushing roller to rotate, crushing the solid fuel into qualified particles. At this time, the crushed solid fuel falls into the feeding trough through the second connecting pipe, and then enters the control tube again through the feeding trough, and is then fed into the combustion furnace. The filter plate can automatically send the fuel with the required particle size into the combustion furnace without the need for manual preliminary screening, which greatly improves the efficiency of fuel processing. At the same time, for the larger solid fuel with the required particle size, it is pushed into the crushing trough by the push plate for crushing treatment, so that it can be used in the combustion furnace after reaching the qualified particle size. This reduces manual intervention, reduces labor intensity, and solves the problems in the existing technology. Attached Figure Description

[0038] Given the current technology, existing combustion control devices, which use screens to intercept unqualified solid fuels and then crush the intercepted fuels to the appropriate particle size before combustion, lead to a prolonged production process, affecting production efficiency. Furthermore, operating the screening and crushing equipment requires specialized operators, increasing labor costs.

[0039] like Figure 1-4 As shown, this utility model embodiment provides a combustion particle size control device adapted for solid fuel combustion, including...

[0040] Feeding assembly 1;

[0041] Feeding assembly 1 includes: control tube 11;

[0042] Control component 2, control component 2 includes:

[0043] Filter plate 21 is fixed inside the upper end of control tube 11;

[0044] The first filter hole 211 is formed on the surface of the filter plate 21;

[0045] The crushing trough 22 is located on the upper side of the control pipe 11;

[0046] The first connecting pipe 23 is fixed to one side of the control pipe 11 and is in communication with the crushing tank 22;

[0047] The break frame 24 is fixedly connected to the lower surface of the first connecting pipe 23;

[0048] The second connecting pipe 25 is fixedly inserted through the lower surface of the crushing frame 24;

[0049] The feed chute 26 is located at the lower end of one side of the control pipe 11 and is set in correspondence with the crushing chute 22;

[0050] The filter plate 21 performs preliminary screening of the incoming solid fuel. The first filter hole 211 on its surface allows fuel with the required particle size to pass through and enter the combustion furnace, while larger fuel with the required particle size is intercepted on the upper surface. The crushing tank 22 is used to receive and temporarily store larger solid fuel with the required particle size. The first connecting pipe 23 guides the fuel in the crushing tank 22 to the crushing frame 24 for crushing.

[0051] The crushing frame 24 is the place where fuel is crushed. A crushing roller 241 is installed inside. When the motor 242 drives the crushing roller 241 to rotate, the fuel is crushed into smaller particles in the crushing frame 24. The second connecting pipe 25 is used to transport the crushed qualified fuel from the crushing frame 24 to the feed trough 26.

[0052] A feed frame 12 is fixed to the upper surface of the control tube 11, and solid fuel enters from the feed frame 12;

[0053] An electric push rod 27 is fixed on the other side of the control tube 11. The output end of the electric push rod 27 passes through the control tube 11, and a push plate 28 is fixed to the output end of the electric push rod 27. The push plate 28 is in contact with the filter plate 21.

[0054] A crushing roller 241 is rotatably installed inside the crushing frame 24, and a motor 242 is fixed on one side of the crushing roller 241. The first connecting pipe 23 and the second connecting pipe 25 are obliquely fixed on one side of the control pipe 11.

[0055] A fixed platform 271 is fixed to the lower surface of the electric push rod 27, and one side of the fixed platform 271 is fixed to the outer surface of the control tube 11.

[0056] When larger solid fuel particles that do not meet the specified size accumulate on the upper surface of the filter plate 21, the electric push rod 27 is activated, and its output end pushes the push plate 28 to move. The push plate 28 pushes the larger fuel particles into the crushing trough 22 for crushing.

[0057] In operation, fixed fuel is fed into the control pipe 11 through the feed frame 12. The filter plate 21 then feeds the fixed fuel with the required particle size into the combustion furnace, while the fixed fuel with the required particle size remains on the upper surface of the filter plate 21. Next, the electric push rod 27 is activated by the external controller. The electric push rod 27 drives the push plate 28 to move on the filter plate 21, pushing the larger solid fuel particles into the crushing trough 22. The fixed fuel then enters the first connecting pipe 23 from the crushing trough 22 and flows into the crushing frame 24 from the first connecting pipe 23. Then, the motor 242 is activated, driving the crushing roller 241. The rotation process crushes solid fuel into qualified particles. The crushed solid fuel then falls into the feed trough 26 through the second connecting pipe 25, and re-enters the control pipe 11 through the feed trough 26 before being fed into the combustion furnace. The filter plate 21 automatically feeds fuel that meets the particle size requirements into the combustion furnace, eliminating the need for manual preliminary screening and greatly improving the efficiency of fuel processing. At the same time, for larger solid fuels that do not meet the particle size requirements, the pusher plate 28 pushes them into the crushing trough 22 for crushing, so that they reach the qualified particle size before being put back into the combustion furnace for use, reducing manual intervention and labor intensity.

[0058] Specifically, such as Figure 1-5 As shown,

[0059] Adjustment component 3; Adjustment component 3 includes: mounting groove 31, which is opened at the upper front end of control tube 11 and located in the middle of filter plate 21; placement groove 32, which is opened in the middle of one side of filter plate 21 and directly opposite to mounting groove 31; and adjustment plate 33, which is slidably placed inside mounting groove 31 and placement groove 32.

[0060] The surface of the adjustment plate 33 is provided with a second filter hole 331, and the diameter of the second filter hole 331 is smaller than that of the first filter hole 211, and the first filter hole 211 and the second filter hole 331 are positively aligned.

[0061] A fixing groove 34 is provided on one side of the adjusting plate 33, and a fixing frame 35 is fixed on one side of the control tube 11. A spring 36 is fixed inside the fixing frame 35, and a locking post 37 is fixed at the lower end of the spring 36, with the end of the locking post 37 extending into the fixing groove 34.

[0062] The placement groove 32 and the installation groove 31 work together to place and fix the adjustment plate 33, so that the adjustment plate 33 can be smoothly installed and moved. The main function of the adjustment plate 33 is to adjust the particle size of the fuel according to the actual production needs. By inserting adjustment plates 33 with different apertures into the installation groove 31, the aperture size through which the fuel passes is changed, thereby achieving the screening of fuel particle size.

[0063] The fixing groove 34 provides accurate limiting and positioning for the locking post 37, and the fixing frame 35 provides stable space for the spring 36. The main function of the spring 36 is to provide elastic force so that the locking post 37 can be tightly locked into the fixing groove 34, thereby fixing the adjusting plate 33 on the control tube 11.

[0064] When in use, if it is necessary to change the particle size of the fixed fuel, the operator can press the locking post 37 upwards, compressing the spring 36 within the fixing frame 35. At this time, the locking post 37 will retract from the fixing groove 34, and the adjusting plate 33 can be pulled out from the mounting groove 31 and the placement groove 32. Then, adjusting plates 33 with different apertures can be inserted into the mounting groove 31. When the fixing groove 34 and the locking post 37 are aligned, the spring 36 will quickly recover its deformation under the elastic force of the spring 36, causing the locking post 37 to engage in the fixing groove 34, thus fixing the adjusting plate 33. The operator can change the particle size of the fixed fuel simply by pressing the locking post 37 and pulling out and inserting the adjusting plate 33. The whole process does not require complicated tools or cumbersome steps, saving operation time and labor costs.

[0065] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
